Micro-Rnas Are Related To Epicardial Adipose Tissue In Participants With Atrial Fibrillation: Data From The Mirhythm Study, Khanh-Van T. Tran, Jordan Majka, Saket Sanghai, Mayank Sardana, Darleen M. Lessard, Zachary J. Milstone, Kahraman Tanriverdi, Jane E. Freedman, Timothy P. Fitzgibbons, David D. Mcmanus

Introduction: Epicardial adipose tissue (EAT) has been linked to incidence and recurrence of atrial fibrillation (AF), but the underlying mechanisms that mediate this association remain unclear. Circulating microRNAs (miRNAs) contribute to the regulation of gene expression in cardiovascular diseases, including AF. Thus, we sought to test the hypothesis that circulating miRNAs relate to burden of EAT.

Methods: We examined the plasma miRNA profiles of 91 participants from the miRhythm study, an ongoing study examining associations between miRNA and AF. We quantified plasma expression of 86 unique miRNAs commonly expressed in cardiomyocytes using quantitative reverse transcriptase polymerase chain reaction (qPCR). From ...

A Receptor Of The Immunoglobulin Superfamily Regulates Adaptive Thermogenesis, Carmen Hurtado Del Pozo, Randall H. Friedline, Hye Lim Noh, Jason K. Kim, Ann Marie. Schmidt

Open Access Articles

Exquisite regulation of energy homeostasis protects from nutrient deprivation but causes metabolic dysfunction upon nutrient excess. In human and murine adipose tissue, the accumulation of ligands of the receptor for advanced glycation end products (RAGE) accompanies obesity, implicating this receptor in energy metabolism. Here, we demonstrate that mice bearing global- or adipocyte-specific deletion of Ager, the gene encoding RAGE, display superior metabolic recovery after fasting, a cold challenge, or high-fat feeding. The RAGE-dependent mechanisms were traced to suppression of protein kinase A (PKA)-mediated phosphorylation of its key targets, hormone-sensitive lipase and p38 mitogen-activated protein kinase, upon beta-adrenergic receptor stimulation-processes ...

Mtorc2/Akt Activation In Adipocytes Is Required For Adipose Tissue Inflammation In Tuberculosis, Nuria Martinez, Catherine Y. Cheng, Natkunam Ketheesan, Aidan Cullen, Yuefeng Tang, Josephine Lum, Kim West, Michael Poidinger, David A. Guertin, Amit Singhal, Hardy Kornfeld

Open Access Articles

BACKGROUND: Mycobacterium tuberculosis has co-evolved with the human host, adapting to exploit the immune system for persistence and transmission. While immunity to tuberculosis (TB) has been intensively studied in the lung and lymphoid system, little is known about the participation of adipose tissues and non-immune cells in the host-pathogen interaction during this systemic disease.

METHODS: C57BL/6J mice were aerosol infected with M. tuberculosis Erdman and presence of the bacteria and the fitness of the white and brown adipose tissues, liver and skeletal muscle were studied compared to uninfected mice.

FINDINGS: M. tuberculosis infection in mice stimulated immune cell infiltration ...

Generation Of Functional Human Adipose Tissue In Mice From Primed Progenitor Cells, Raziel Rojas-Rodriguez, Jorge Lujan-Hernandez, So Yun Min, Tiffany Desouza, Patrick Teebagy, Anand Desai, Heather Tessier, Robert Slamin, Leah Siegel-Reamer, Cara Berg, Angel Baez, Janice F. Lalikos, Silvia Corvera

Adipose tissue (AT) is used extensively in reconstructive and regenerative therapies, but transplanted fat often undergoes cell death, leading to inflammation, calcification, and requirement for further revision surgery. Previously, we have found that mesenchymal progenitor cells within human AT can proliferate in three-dimensional culture under proangiogenic conditions. These cells (primed ADipose progenitor cells, PADS) robustly differentiate into adipocytes in vitro (ad-PADS). The goal of this study is to determine whether ad-PADS can form structured AT in vivo, with potential for use in surgical applications. Grafts formed from ad-PADS were compared to grafts formed from AT obtained by liposuction after implantation ...

Decomposition Of Pig Carcasses At Varying Room Temperature, Jacqueline Abad Santos

Themis: Research Journal of Justice Studies and Forensic Science

The goal of this study is to assess the qualitative scoring of decomposition scales with statistical analysis while also determining which indoor environment will decompose the fastest. When comparing the three indoor environments, water decomposition appears to be the fastest, but the method of analysis for this study determines that using decomposition scales to analyze such environments may produce statistically insignificant results. For this study, piglets were put in a dry steel tub, a water filled steel tub, and a suitcase. These were recorded using photographs for 25 days and then scored using decomposition scales. The total score was divided ...

Innovative Care Of Individuals In The Athletic Training Room: A Case Series, Kathryn E. Young

Senior Honors Projects, 2010-current

This work follows three unique cases of athletic injuries and/or injuries in patients. These cases were selected because of the innovative nature of the rehabilitation process conducted by the sports medicine team via the athletic training room or the unique nature of the injury/case.

The first is a concussion sustained from a motor vehicle accident in a collegiate female thrower. This is unique because it’s a non-sport related concussion handled as an athletic trainer would handle a sports related concussion. It also demonstrates a new unique protocol for concussion management.

The second case is a patient with ...

Currently there is not any one specific solution for the condition although many have been proposed. Throughout the thesis I will closely examine former research studies, current solutions proposed, and propose my own study and solution based on research ...

Exercise Rescues Gene Pathways Involved In Vascular Expansion And Promotes Functional Angiogenesis In Subcutaneous White Adipose Tissue, So Yun Min, Heather Learnard, Shashi Kant, Olga Gaelikman, Raziel Rojas-Rodriguez, Tiffany Desouza, Anand Desai, John F. Keaney Jr., Silvia Corvera, Siobhan M. Craige

Open Access Articles

Exercise mitigates chronic diseases such as diabetes, cardiovascular diseases, and obesity; however, the molecular mechanisms governing protection from these diseases are not completely understood. Here we demonstrate that exercise rescues metabolically compromised high fat diet (HFD) fed mice, and reprograms subcutaneous white adipose tissue (scWAT). Using transcriptomic profiling, scWAT was analyzed for HFD gene expression changes that were rescued by exercise. Gene networks involved in vascularization were identified as prominent targets of exercise, which led us to investigate the vasculature architecture and endothelial phenotype. Vascular density in scWAT was found to be compromised in HFD, and exercise rescued this defect ...

Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente

Graduate Student Research Symposium

Usually not diagnosed until open laparotomy, aortoduodenalfistulas (ADF) are one of the rarest complications of intestinal transplant surgery. With an incidence rate of only 0.04% at autopsy and only 250 documented cases since the early 1800’s, aortoduodenal fistulas are the most deadly complications of intestinal transplantation with a mortality rate of 100% without surgical intervention. A 39 year old, two-time multi-visceral transplant African American female patient suffered from a primary aortoduodenal fistula formation in a primary modified multi-visceral transplant aortic stump graft site. With emergency open laparotomy repair, revascularization of the secondary multi-visceral transplant was performed, saving the ...

The Tec Kinase Itk Is Essential For Ilc2 Survival And Epithelial Integrity In The Intestine, Hyoung-Soo Cho, Andrea Reboldi, Jason A. Hall, Leslie J. Berg

Open Access Articles

Innate lymphoid cells (ILC) are lymphocytes that lack an antigen-specific receptor and are preferentially localized in non-lymphoid tissues, such as mucosal barriers. In these locations ILC respond to tissue perturbations by producing factors that promote tissue repair and improve barrier integrity. We show that mice lacking the Tec kinase ITK have impaired intestinal tissue integrity, and a reduced ability to restore homeostasis after tissue damage. This defect is associated with a substantial loss of Type 2 ILC (ILC2) in the intestinal lamina propria. Adoptive transfer of bone marrow ILC2 precursors confirms a cell-intrinsic role for ITK. Intestinal ILC2 numbers in ...

Effects Of Acute Hypoxia On Danio Rerio, Karly Crail

Williams Honors College, Honors Research Projects

The purpose of this research experiment was to determine the effects of acute hypoxia on the embryonic zebrafish (Danio rerio) cardiovascular system and assess the critical oxygen level at which embryonic function is compromised. This goal was achieved by exposing embryos to decreasing oxygen concentrations, (6.0 mg/L-0 mg/L) and observing the heart under an inverted microscope. Data analysis was conducted to determine end systolic volume, end diastolic volume, stroke volume, heart rate, and cardiac output. It was hypothesized that hypoxia would stimulate cardiac activity, because in early developmental stages, tissues are supplied with oxygen through bulk diffusion ...

Kinesiophobia And Its Impairment Of Successful Return To Sport After Anterior Cruciate Ligament Injury And Reconstruction, Gabrielle Boulding

Faculty of Applied Health and Community Studies - Exceptional Student Work

The rehabilitation of an athlete after an anterior cruciate ligament (ACL) injury includes both physical and psychological barriers. One such psychological barrier is kinesiophobia, more commonly referred to as the fear of reinjury. All individuals experience some level of kinesiophobia, or fear of reinjury, related to the return to sport after ACL injury and reconstruction. Kinesiophobia can have a negative impact on an athlete’s short-term rehabilitation and long-term goals of return to sport. In many cases the fear of reinjury has been found to be one of the key reasons that an athlete does not return to sport or ...

The Relationship Between Feeding Type And Temporomandibular Joint Morphology In Superfamily Musteloidea, Travis L. Garvin

Masters Theses

Many studies have focused on the soft tissue analysis of carnivores and have demonstrated a relationship between feeding biomechanics and feeding types. Herbivores and omnivores rely heavily on anteroposterior and helical movement of the mandible and teeth for the breakdown of fibrous foods resulting in a flat mandibular fossa while the function of the carnivore TMJ is different, as they need a much stable joint for ripping and tearing of the flesh. I aim to look at whether the bony morphology of the temporomandibular joint (TMJ) can be directly related to feeding type, specifically in the superfamily Musteloidea. I sampled ...

21 - Cigarette Smoke Exposure Upregulation Of Pge₂ Expression In The Bladder, Jessica Nix

Georgia Undergraduate Research Conference (GURC)

CIGARETTE SMOKE EXPOSURE UPREGULATION OF PGE₂ EXPRESSION IN THE BLADDER

Jessica Nix, Jane McHowat, Shannon Kispert

Cigarette smoking remains the leading cause of preventable death and disease in the United States. Despite known risks, 42.1 million Americans continue to smoke, making research into tobacco-related pathologies relevant and necessary. We previously discovered that cigarette smoke exposure leads to tumor progression in the breast via platelet activating factor (PAF) and other phospholipase A₂ (PLA₂) metabolic pathways. These results led us to examine the PLA₂ metabolite, prostaglandin E₂ (PGE₂). We observed the expression of PGE₂ in mouse bladder and human heart ...

Crispr-Delivery Particles Targeting Nuclear Receptor-Interacting Protein 1 (Nrip1) In Adipose Cells To Enhance Energy Expenditure, Yuefei Shen, Jessica L. Cohen, Sarah M.

RNA-guided, engineered nucleases derived from the prokaryotic adaptive immune system CRISPR-Cas represent a powerful platform for gene deletion and editing. When used as a therapeutic approach, direct delivery of Cas9 protein and single-guide RNA (sgRNA) could circumvent the safety issues associated with plasmid delivery and therefore represents an attractive tool for precision genome engineering. Gene deletion or editing in adipose tissue to enhance its energy expenditure, fatty acid oxidation, and secretion of bioactive factors through a "browning" process presents a potential therapeutic strategy to alleviate metabolic disease. Here, we developed "CRISPR-delivery particles," denoted CriPs, composed of nano-size complexes of Cas9 ...

The Effects Of Tracheal Occlusion On Wnt Signaling In A Rabbit Model Of Congenital Diaphragmatic Hernia, Martina M. Mudri

Electronic Thesis and Dissertation Repository

Purpose: Tracheal occlusion (TO) reverses pulmonary hypoplasia (PH) in congenital diaphragmatic hernia (CDH), but its effect on epithelial-mesenchymal transition (EMT) in lung development remains poorly understood. The purpose of this study was to a) confirm the CDH rabbit model produced PH which was reversed by TO and b) determine the effects of CDH +/- TO on EMT pathways.

Methods: CDH was created at 23 days, TO at 28 days and lung collection at 31 days gestation in fetal rabbits. Lung body weight ratio (LBWR), mean terminal bronchiole density (MTBD), and expression of mRNA and micro-RNA was determined.

Results: Fifteen CDH, 15 ...

Primary Cardiac Lymphoma: Importance Of Tissue Diagnosis, Lauren Mendelson, Emily Hsu, Hojune Chung, Andrew Hsu

Open Access Articles

Primary cardiac lymphoma (PCL) is a rare disease entity that can present with severe cardiac and cardioembolic symptoms. We present a 79-year-old male with history of polymalgia rheumatica on chronic prednisone who presented with a two-week history of progressively worsening dyspnea, cough, and a 10 pound weight loss. Transthoracic echocardiogram (TTE) and computed tomography (CT) of the chest showed a large mediastinal mass with invasion of the pericardium. A biopsy of an abdominal soft-tissue mass confirmed the diagnosis of PCL. The patient was treated with two cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) which was complicated by ...

Methods For High-Dimensonal Analysis Of Cells Dissociated From Cyropreserved Synovial Tissue, Laura T. Donlin, Ellen M. Gravallese, Jennifer H. Anolik

Open Access Articles

BACKGROUND: Detailed molecular analyses of cells from rheumatoid arthritis (RA) synovium hold promise in identifying cellular phenotypes that drive tissue pathology and joint damage. The Accelerating Medicines Partnership RA/SLE Network aims to deconstruct autoimmune pathology by examining cells within target tissues through multiple high-dimensional assays. Robust standardized protocols need to be developed before cellular phenotypes at a single cell level can be effectively compared across patient samples.

METHODS: Multiple clinical sites collected cryopreserved synovial tissue fragments from arthroplasty and synovial biopsy in a 10% DMSO solution. Mechanical and enzymatic dissociation parameters were optimized for viable cell extraction and surface ...
